Date: Sat, 5 Apr 2008 19:54:28 -0700 From: "Chris Peterson" To: sdl@lists.libsdl.org Subject: [SDL] [PATCH] SDLMain.m: fix a bug and some warnings for Mac OS X Here are some small fixes for the src/main/macosx/SDLMain.m source file used by Mac OS X apps: 1. setupWorkingDirectory() called chdir() within an assert(), which gets compiled out in non-debug builds. 2. When some of gcc's optional warnings are enabled, it complains about some implicit casts and the use of #import in SDLMain.m.
